子囊

Any of various fleshy, ascomycetous, edible fungi, chiefly of the genus Tuber, that grow underground on or near the roots of trees and are valued as a delicacy.

块菌一种肉质可食的子囊真菌，主要是指生长在地下或树根附近并被视作美味的块茎属

The paper researched by 24 Saccharomyces cerevisiae strains and three kinds of related ascomycetous yeasts in the Angel Yeast Co.,L td,by electrophoresising and sequencing, ribosomal DNA ITS-1 sequences can analysis their's phylogenetic systematics relationship.

本论文以安琪酵母股份有限公司有代表性的酿酒酵母属中24株酿酒酵母及相关3种子囊菌酵母为研究对象，通过对所选取酵母菌株的核糖体DNA ITS-1序列进行电泳和克隆测序，分析出它们之间的系统学关系。

When the cultures of Trichoderma isolates which possess the stronger antagonistic ability to S.sclerotiorum are introduced into the soil, the sclerotia burried in this soil is to decay six months later, the carpogenic germination of sclerotia that has not decayed reduces sharply.

将拮抗作用强的木霉菌株培养物导入土壤后，埋入土壤中的菌核多数将发生腐烂，即使未腐烂的菌核其产子囊盘萌发能力也大大降低。

A soil temperature of 18-20℃ in ten days before the initial emergence of apothecia was an important prerequisite factor determining carpogenic germination.

棚内北半侧土温较低，是子囊盘出土比南半侧早、出盘持续期长，数量多和发病重的重要原因。

Most of these fungi reproduce by conidia produced by mitosis.

的确，现在已知青霉菌的有性阶段，以前则认为它与子囊菌是截然不同的。

The results demonstrated that sexual reproduction capacity between isolates derived from ascospores and conidia were different, and at least partially determined by their genetic differences.

结果表明，由子囊孢子和分生孢子萌发获得的菌株的有性生殖能力具有显著差异，这可能决定于不同的遗传特性。

In this paper, the sexual reproduction capacity of Orbiliaceous anamorphs derived from ascospores and asexual conidia were evaluated.

本文评估了分离自子囊孢子和分生孢子的圆盘菌科无性型有性生殖能力。

By morphological and molecular methods the strain B3 was identified as Diaporthe and could exist under acidic condition, whose laccase had good thermostability.

通过形态学观察及测定其rDNA ITS序列对菌株B3进行鉴定，该菌株属于子囊菌亚门的腐皮壳属。

V Middle infectious varieties: The disease spots area is from 21 percent to 40 percent of leaf area in Erysiphe peak period.

高感品种：发病盛期叶片病斑面积占叶面积的40％以上，茎杆、叶片全染病，孢子囊破裂。

In order to understand the validity of the resistant genes to wheat powdery mildew in Shanxi province, in greenhouse condition, cleistothecia released ascospores were used to infect wheat seedling. The frequencies of virulence genes for 166 isolates of Erysiphe graminis f. sp. tritici from different ecological areas of Shanxi province were tested.

为明确小麦白粉病抗性基因在山西省的有效性，在温室条件下，通过闭囊壳释放子囊孢子侵染麦苗发病，利用28个已知抗病基因品种对分离自山西省不同生态区的166个小麦白粉病菌株进行了毒性基因频率测定。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
